Motion compensation method, image encoding method, image decoding method, image encoding device and image decoding device

A motion compensation method comprises: a complementing step of complementing the pixel values of a reference block when motion compensation is performed for a target block, which is included in a plurality of tiles, by use of a prediction mode using the motion vectors of peripheral blocks of the target block and further when the motion vectors of the peripheral blocks refer to the reference block included in tiles different from the target tiles in which the target block is included; and a motion compensating step of performing the aforementioned motion compensation by use of the aforementioned pixel values as complemented.
